Think sharks are scary? They're downright cuddly compared to the Bathynomus giganteus, a very terrifying (and very real) sea creature that recently surfaced from the deep.

So, what the heck is it? According to an article from Fox News, the Bathynomus giganteus (henceforth known as "Bart") is a type of giant isopod, "a large crustacean that dwells in deep Atlantic and Pacific waters." It passes the time by feeding on "dead whales, fish, and squid."

Ol' Bart attached itself to a submarine that was exploring the ocean floor. When the sub surfaced, people got an unexpected look at the slithery stowaway. The creature is a pinkish in color, two and a half feet long, and wouldn't be out of place in an Ed Wood movie (no offense, Bart).

The story was originally posted on Reddit by a guy who works for the submarine company. It quickly went viral from there.
